RESULTS OF STAND TESTS FOR WEAR RESISTANCE OF PLOUGHSHARE AFTER STRENGTHENING WITH ELECTROMECHANICAL HARDENING

Abstract

The work analyzed the conditions for testing the plowshares for wear resistance, on the basis of which a test stand is proposed and a description of its design features is given. The methods and results of comparative wear tests of samples of standard plowshares and plowshares strengthened by electromechanical hardening are given. Tests have confirmed the high efficiency of electromechanical hardening to increase the wear resistance of plowshares. Regression equations in natural and coded values are obtained, which determine the influence of independent factors on the wear of plowshare samples after electromechanical hardening.
